Why does my smoke alarm beep or chirp?

 



  • The battery may be loose or improperly installed. Verify that a battery of the recommended type is securely installed
  • The smoke alarm sensing chamber may be dirty. Dust and insects can collect in the sensing chamber of the alarm. An accumulation of dust in the sensing chamber can cause the unit to chirp. It is good practice to clean the smoke alarm when you change the battery using a vacuum cleaner.
  • The alarm may have a low battery. Change the battery.
  • The alarm may have reached its end of life and should be replaced.
